Introduce a new health check endpoint at `/api/health`. This endpoint returns a JSON response indicating the server's status and configuration details, such as the port, data path, and configured URLs for external services. This change also refactors the application setup by: - Creating a `lib.rs` file to house the `create_router` function, making it reusable for both the main application and integration tests. - Moving configuration loading logic into `main.rs` and passing it as a shared state (`Arc<Config>`) to the router. - Adding a unit test (`health_test.rs`) to verify the functionality of the health check endpoint. - Updating `Cargo.toml` and `Cargo.lock` to include the `tower` dependency, which is used for testing.
